To not make you answer yourself again: The chances are low.
I gave away the map to another map maker years after I suffered a huge data loss while working on the v0.6X series.
Actually I gave away the map three times in total.
The last map maker whom I gave the rights to continue the work was the most motivated one and even created something that at least barely worked in the end, however, even he disappeared. So it is again just me as far as I know.
It is very unlikely but not entirely impossible that development of this map is going to be continued.
Let's see what the future of WarCraft III: Reborn brings to our tables.
